The height of the rows 7,..,23 is in a certain Excel sheet to low.

How can I increase the height (for only these rows) by 8 pixels ?

Or more general: If I mark rows n,....,m
How can I make them x pixels (resp y millimeter) higher ?

Here is some Windows-only code to resize rows which you pre-selected by a
specified number of pixels. Copy/paste the following code into your code
window and then run (Alt+F8) the IncreaseRowHeightsInPixels subroutine from
your spreadsheet after selecting the rows you want to increase by the number
of pixels you will specify when asked...

Private Declare Function GetDC Lib "user32" _
(ByVal hwnd As Long) As Long

Private Declare Function GetDeviceCaps Lib "gdi32" _
(ByVal hDC As Long, ByVal nIndex As Long) As Long

Private Declare Function ReleaseDC Lib "user32" _
(ByVal hwnd As Long, ByVal hDC As Long) As Long

Private Const LOGPIXELSY = 90 'Pixels/inch in Y

'A point is defined as 1/72 inches
Private Const POINTS_PER_INCH As Long = 72

'The size of a pixel, in points
Public Function PointsPerPixel() As Double
Dim hDC As Long
Dim lDotsPerInch As Long
hDC = GetDC(0)
lDotsPerInch = GetDeviceCaps(hDC, LOGPIXELSY)
PointsPerPixel = POINTS_PER_INCH / lDotsPerInch
ReleaseDC 0, hDC
End Function

Sub IncreaseRowHeightsInPixels()
Dim R As Range
Dim Answer As Double
Answer = InputBox("How may pixels higher do you want?")
For Each R In Selection.Rows
R.RowHeight = R.RowHeight + Answer * PointsPerPixel
Next
End Sub
